Abstract
BACKGROUND The association between muscle defects and hypertension is well-established. However, the absence of pertinent and uncomplicated clinical indicators presents a challenge. Relative muscle strength (RMS) may offer a viable indicator. This study aimed to explore the association between RMS and hypertension. METHODS A total of 12,720 individuals aged ≥ 45 years from the 2011 wave of the China Health and Retirement Longitudinal Study (CHARLS) were included. Grip strength was recorded and appendicular skeletal muscle mass (ASM) was estimated using a validated mathematical formula. The RMS was calculated as the ratio of grip strength to ASM. Hypertension was determined based on previous diagnosis, history of hypertension medication use, and current blood pressure. Logistic regression models were employed to investigate the relationship between RMS and hypertension. RESULTS The prevalence of hypertension was 41.7% (5,307/12,720 patients). RMS was negatively correlated with hypertension with an OR (95% CI) of 0.68 (0.59-0.79) for males, 0.81 (0.73-0.90) for females, and 0.78 (0.72-0.85) for the entire population after adjusting for related covariates including age, education, marital history, smoking history, drinking history, diabetes, hyperlipidemia, and obesity. The trend test showed a linear association among males, females, or the entire population. Stratified analysis showed a consistent negative correlation between RMS and hypertension. CONCLUSIONS Higher RMS is an independent protective factor against hypertension and efforts to promote RMS may be beneficial for the prevention and management of hypertension.

Abstract
OBJECTIVE To identify the prevalence of non-communicable chronic diseases: arterial hypertension, diabetes mellitus, and associated risk factors in long-lived elderly people from three Brazilian regions. METHODS This is a multicenter, cross-sectional, and comparative study conducted with elderly people aged 80 years or older. RESULTS Higher prevalence of arterial hypertension were observed among those who use polypharmacy (75.7%), among elderly people aged between 80 and 84 years (33.9%), as well as in elderly people who are overweight (78.2%). The prevalence of diabetes was 24% (RP: 0.76; 95% CI: 0.59-0.98) lower among women compared to men and 2.15 times higher among those who use five or more medications (RP: 2.15; 95% CI: 1.63-2.85). CONCLUSIONS In our sample, polypharmacy, body weight, and gender determine the prevalence of non-communicable chronic diseases: arterial hypertension and diabetes mellitus in long-lived elderly people.

Abstract
AIM There are few studies comparing the effects of geriatric syndromes and abnormalities in nutritional status and body composition on outcomes among older individuals who have been previously hospitalized. Our study aimed to evaluate the frequency and diagnosis of geriatric syndromes, low muscle quality, and nutritional status in hospitalized older individuals, and to examine their impact on both short- and long-term outcomes. METHODS This was a prospective study involving older adults (≥60 years). We assessed nutritional status, muscle quality, sarcopenia, and frailty. The outcomes were functional dependence, length of hospital stay, transfer to the Intensive Care Unit, number of readmissions, and mortality. Multivariate analysis was conducted to identify independent risk factors. RESULTS Even after adjustment for age and sex, increased risk of death was associated with possible undernourishment, sarcopenia, low muscle quality, and frailty (P < 0.05), but not the length of hospital stay (P > 0.05). Our multivariate analysis showed that frailty was independently associated with mortality and functional dependence. Low muscle quality was independently associated with functional dependence. CONCLUSIONS Geriatric syndromes, abnormalities in body composition, and the overall nutritional status of older patients are important risk factors for adverse outcomes, including functional dependence and mortality. These findings emphasize the need for interventions to improve muscle quality, prevent and treat malnutrition and sarcopenia, and address frailty in hospitalized patients.

Abstract
BACKGROUND We aimed to determine whether a history of falls before admission affected physical activity levels and sedentary behavior negatively after implementing a behavior modification approach in patients with minor ischemic stroke. METHODS This study constituted a secondary analysis of an intervention trial. In the intervention study, patients with minor ischemic stroke were randomly assigned to two groups: intervention and control groups. The intervention group was encouraged to reduce sedentary behavior during hospitalization and after discharge, while the control group was encouraged to increase physical activity levels solely during hospitalization. The study included 52 patients who completed the intervention trial. The exposure factor examined was a history of falls. Upon admission, patients were queried about any falls experienced in the year preceding admission and subsequently classified into fall and non-fall groups based on their responses. The primary outcome of interest focused on changes in physical activity levels (step count, light-intensity physical activity, and moderate-to-vigorous-intensity physical activity) and sedentary behavior. Measurements were obtained at two time points: before the intervention, during hospitalization (baseline), and 3 months after discharge (post-intervention). RESULTS Only a significantly lower change in the number of steps taken in the fall group than in the non-fall group was found. CONCLUSION Those with a history of falls showed a lesser change in the number of steps taken before and after implementing a behavior change approach compared with those without a history of falls. Those with a history of falls may have engaged in activities other than walking.

Field-Based Estimates of Muscle Quality Index Determine Timed-Up-and-Go Test Performance in Obese Older Women. Clin Interv Aging 2023; 18:293-303.

Abstract
Objective The muscle quality index (MQI) is associated with numerous health outcomes in adults; however, the effects of distinct MQI on functional capacity in obese older women have not yet been fully investigated. Thus, we investigated the contribution of different muscle quality indices on TUG performance prediction in obese older women. We secondarily evaluated the association between MQI, aerobic capacity performance (Treadmill performance and 6-minute walk test), and obesity indices (BMI, body fat percentage, and neck, waist, and hip circumference). Methods Participants included 64 obese older women (mean age 67.05 ± 5.46 years, body fat ≥ 35%). General anthropometric, health history, body composition, treadmill exercise, and functional test (Time up and go) measures were collected. A hydraulic dynamometer was used to assess muscle strength, and Dual Energy X-ray Absorptiometry (DXA) to identify body fat percentage. The field MQI was defined as the highest reading divided by the subject's body mass index (BMI), while the laboratory MQI was obtained by the ratio of grip strength to the entire arm muscle in kilograms measured by DXA. A hierarchical multiple regression was performed to predict TUG-test performance. Results An increase in field MQI of one unit is associated with a decrease of 2.59 seconds in the TUG test (β = -0.540; p = 0.004). There was no association between laboratory MQI and TUG performance (β = 0.067; p = 0.712). Furthermore, field MQI displays a positive correlation (p < 0.05) with aerobic capacity performance (6-minute walk test and peak O2 consumption) and a negative correlation (p < 0.05) with diverse obesity indices (neck and waist circumference, body fat, and BMI). Conclusion MQI displayed an important prediction with TUG-test, a positive correlation with aerobic capacity, and a negative correlation with obesity indices.

Abstract
Objectives To determine if anthropometric variables, body composition, medication and gender are associated with functional performance and to compare these variables between octogenarians with high and low functional performance. Methods Observational, cross-sectional study. Weight, height, body mass index (BMI), waist circumference (WC), and waist-to-height ratio (WHtR) were evaluated. Handgrip strength (HGS) was assessed. Participants’ body composition was assessed by dual-energy X-ray absorptiometry (DXA) and functional performance by Short Physical Performance Battery (SPPB). A binomial logistic regression was performed. Results One hundred and twenty-two octogenarians were included and separated into high and low function groups. The high function group showed lower values of WHtR (mean difference [MD] = 0.047, P = 0.025) and body fat (BF%) (MD = 3.54, P = 0.032) and higher values of apendicular skeletal muscle mass (ALM) (MD = 3.03, P = 0.001), HGS (MD = 6.11, P = 0.001) and SPPB score (MD = 4.20, P = 0.001). Women were more likely to be classified as low function (OR = 3.66, P = 0.002) and males showed 5.21 odds ratio (P = 0.021) of having high functional performance compared to females. Also, each decrease in age and medication use displayed 1.30 (P = 0.007) and 1.26 odds ratio increases (P = 0.008) in high functional performance. Conclusions Older males display better functional performance than women, and decrements in age and medications increase the high functional performance odds ratio. Octogenarians with high functional performance displayed lower BF measurements and higher values of muscle mass and strength.

Abstract
BACKGROUND Muscle mass and muscle quality assessed by computed tomography (CT) have been associated with poor prognosis in oncology and surgery patients, but the relevant evidence was limited in older patients. We hypothesized that muscle mass and muscle quality indicators derived from opportunistic chest CT images at the 12th thorax vertebra level (T12) could predict in-hospital death, length of hospital stay (hospital LOS), and hospital costs among older patients in acute care wards. METHODS We conducted a prospective cohort study. Older patients admitted to the acute geriatric wards of a teaching hospital were continuously recruited. Chest CT images were analysed using SliceOmatic software. The skeletal muscle area, skeletal muscle radiodensity, and intermuscular adipose tissue (IMAT) at the T12 level were measured. Skeletal muscle index (SMI) was calculated using skeletal muscle area divided by body height squared. RESULTS We included 1135 older patients with a median age of 80 years (interquartile range, 73 to 85 years), 498 (44%) were women, 148 (13%) patients died during hospitalization. The SMI and SMD were negatively correlated to age (ρ = -0.11, P < 0.001, ρ = -0.30, P < 0.001, respectively), whereas the IMAT was positively correlated to age (ρ = 0.27, P < 0.001). Compared with survivors, dead patients had significantly lower SMI in men (P < 0.001) but not in women (P = 0.760). After adjusting for sex and other potential confounders, the SMI [increased per 1 cm2 /m2 , odds ratio (OR) 0.96, 95% confidence interval (CI) 0.93 to 0.99] and SMD (increased per 1 Hounsfield unit, OR 0.93, 95% CI 0.90 to 0.96) were negatively and independently associated with in-hospital death, whereas the IMAT (increased per 1 cm2 , OR 1.09, 95% CI 1.05 to 1.14) was independently and positively associated with in-hospital death. None of the SMI, SMD, or IMAT was significantly related to long hospital LOS or increased hospital costs. CONCLUSIONS Chest CT-derived muscle mass indicator (T12 SMI) and muscle quality indicators (T12 SMD and T12 IMAT) may serve as prognostic factors for predicting in-hospital death among older inpatients. Opportunistic chest CT images might be an overlooked resource for measuring muscle mass and muscle quality and for predicting short-term prognosis in older inpatients.

Abstract
This study aimed to evaluate the time course and responsiveness of plasma interleukin-6 (IL-6) and creatine kinase (CK) levels following acute eccentric resistance exercise in sedentary obese older women with a different muscle quality index (MQI). Eighty-eight participants (69.4 ± 6.06 years) completed an acute eccentric resistance exercise (7 sets of 10 repetitions at 110% of 10-repetition maximum with 3 min rest interval). Participants were divided into two groups: high or low MQI according to 50th percentile cut-off. The responsiveness was based on minimal clinical important difference. There were no differences between groups and time on IL-6 and CK levels (p > 0.05). However, the high MQI group displayed a lower proportion of low responders (1 for laboratory and 2 for field-based vs. 5 and 4) and a higher proportion of high responders for IL-6 (7 for laboratory and 6 for field-based vs. 4 and 5) compared to low MQI group. In addition, the high MQI group showed a higher proportion of high responders for CK (11 for laboratory and 9 for field-based vs. 6 and 6) compared to low MQI. A prior MQI screening can provide feedback to understand the magnitude response. Individual responsiveness should be taken into consideration for maximizing eccentric exercise prescription.

Abstract
This study aimed to determine relationships between muscle quality, the ratio of muscle strength to muscle mass, and postural control and compare postural control of older adults with higher and lower muscle quality. Twenty-five older adults had leg muscle quality and postural control with eyes open and closed measured. Linear and non-linear postural control variables were calculated from center of pressure movements. There was a significant canonical correlation between muscle quality and sway complexity, but no relationship between muscle quality and sway magnitude. Higher muscle quality older adults had greater medio-lateral sway complexity than lower muscle quality older adults. These findings suggest that higher muscle quality relates to greater sway complexity in older adults, suggesting maintenance of muscle quality should be considered important to attenuate postural control declines.
